BTN has loose stats

here i wanted to c/r but i wanted to keep his bluffing range in (broadways, spade draws) and medium strength hands 10- AA in. I runed this with snowie and snowie likes to c/r anyways, im actually a bit confused how to treat this spot and why.

I belive here his value range consists on 56s, 57s, 77, 66, 55, for 11 combos of value i dont beat. but i also think he could be doing this with trips, 54s, 34s, 85s, A5, K5s, AA, KK, QQ for 21 value combos i beat. Also, im choping with 98, and beating air like AKs-AQs who might think is good here if it picks up an ace queen or king by the river, guters with spade draws like A9s, A3s, K9s, Q9s. So i think my call is ok, altho snowie doesn´t like it, is there anything wrong in this analysis?
