So, I've seen a lot on plans to try and close distance to Sasuke or the equivalent...but do we have too? Sure Sasuke can bombard freely...until he runs out of ammunition and chakra. And while he and Daisuke probably have similar chakra reserves, and while the Great Fireball is less costly then our Endless Sword, it's still not particularly cheap, nor has Sasuke really pushed it's speed/power/range. More close-to-medium distance, and too slow to get carry out if we can see it and close to disrupt or reverse to dodge. His projectile skill, while superior in quality (and probably more numerous in ammo then normal students would have)...also isn't particularly special. He doesn't have any fancy jutsu to combo it with yet, and his wire skills are still in development and more useful when he has time to set up or a distraction...which won't work in this context or against us respectively (unlike say, Naruto).
Since it's a limited-area spar he can't act with stealth (at least not with a near-peer opponent like us) for an ambush manuver, and his projectiles all have greatly reduced effectiveness (because we can see him, and c + reaction time is much faster then time to hurl a projectile and for it too reach the target at our level).
The biggest problem I can see us having is Daisuke being poor at projectile parrying/dodging even with his focus on CQC since it's not a specific skill we've developed...and I feel that weakness is mitigated somewhat just by the skill all Shinobi show with deflecting 'standard' projectiles and our hidden armor.
Non-standard aren't readily available to Sasuke (doesn't know the jutsu, and doesn't have the right context for wire trickery), leaving only use as a distraction for closing, evading, or Ninjutsu. The former is a bad idea for him, the latter is limited by our sparring area, and the only Ninjutsu he has, the Fireball, isn't quite fast enough to take advantage of an opponent like Daisuke (i.e. one used to Gai training speeds) before we can do the aforementioned close/dodge/nullify.
And in a battle of attrition? Of physical stamina? Sasuke is at a severe disadvantage...one he may not be aware of the full extent of (doesn't see us spar with Gai after all, or the morning 'games', only the lack of exhaustion in basic Academy exercises he himself is above).
All this leaves genjutsu, or blitz tactics...the former of which Daisuke has shown no especial resistance too (though to be frank, I don't know that we actually have any resistance or that Sasuke knows any), while the latter suffers from the same disadvantages of a skilled, armored, only-slightly slower opponent being able to see everything you do and react in far less time.
Of course, standing still does cede advantage to Sasuke, and I know I probably don't remember all his beginning tricks or if he'd keep anything in reserve. A possible alternative might be to take advantage of his lack of knowledge on the Straw Men. Using a kawarimi to abruptly close distance isn't unheard of after all, but it is limited in that it needs to replace with an existing object. Objects that Sasuke is sure to keep aware of and not too close to. Too bad the Straw-men don't have to exist until they do. It may be a temporary surprise, but if we can 'replace' close enough to engage while Sasuke is still reacting to the unexpected manuver (or even better, looking to where conventional Kawarimi targets would be after he sees our hand-seals), then we can blitz up close and take him down before he can recover.
