Ali hates 24s, so maybe not, haha. My Echo's pretty handy for trialsy stuff, although I'm more street-orientated. Stan bosses the purer trials side of things on his Echo. More so when he had a disc on the back than now when he's brakeless, but it was still capable. It's obviously not as good as a 'proper' trials bike though. It pretty much comes down to working out what you/your friend spend more time doing, then buying the frame to suit the majority rather than the minority.
