thanks for the input. that skeg was just huge looking and i stated thinking this will not do slides but it lokks like it woud go straifgt very well. any way it is hard to hold back from modifying stuff sometimes but without experience you can screw stuff up. i saw a 2 oz tank from dubro at the lhs last night looks like it would sort of fit ok. yeh i think yhe .15 will be the most fun at the lhs they had a trick little .15 that they said rips (cant remember the name).thanks a bunch
