Difficult to say. I think it depends on how much and when Kikumaru tries to attack.Kaoz, do you think Shishido will be able to drain Kikumaru's stamina with rising shot? (forcing him to run a lot, and Kikumari's stamina even if it improved isn't that great).
Yeah? It means Hirakoba hit one at some point during the camp, doesn't say anything about him being able to spam it now.Nah, I believe that someone from Rikkai (they didn't see Rokkaku / Higa nor Seigaku / Higa) yelled "THAT'S HIRAKOBA'S TECHNIQUE" when Kite did the Giant Habu.
Well, it's not like Kikumaru scores with every volley he hits.There's not much to say about the claims, really. I still believe that Kai >> Shishido, and that Kikumaru would manage to get to the net without many troubles. If he does, Shishido has nothing to do ( http://i23.mangareader.net/prince-of-tennis/290/prince-of-tennis-646897.jpg ).

Of course this is possible because Ootori is there, but on the flipside, Kikumaru won't get into that position as easily either. Then we have Shishido getting closer to returning Moon Volley from the net than anyone else ever was, so he his Dash shouldn't be underestimated.
Kikumaru's stamina isn't better than Shishido's by far. If you read a couple pages farther from the one you linked, it's said that Kikumaru's stamina was only conserved like that because of Oishi, and Oishi obviously isn't present here.Kikumaru's stamina is better than Shishido's by far too ( http://i22.mangareader.net/prince-of-tennis/291/prince-of-tennis-646921.jpg)

That said, I do agree that if you believe Kikumaru will manage to get to the net the majority of the time without trouble, he'll probably win (not 6-0 or 6-1 though). I don't think it'd be as easy as you seem to imagine though.
