RE: how hard to build SS?
the 3 shoe is better than the 2 most people change them out when there 2 shoe goes bad. the tank on the 25 is allot better than the SS but there is a thread on there that tells you how to mod the SS tank to make it work right..... in my opinion you might be better off going with the 25 than the SS. just make the changes to it that you like.... as for the one way baring it is already in stalled on the SS so that is not something he will need to worry about
