we're building a few really high end competition spec trials bikes:) this aurem is going to be really hard for me to sell, because i love it so much. still need to put the rear hope and headset on there.
are they both around +60 or +65? thats not really high bb for a 20" bike. They should both be fine to learn on. Both very close in strength too, tho the quality, finish, and alignment on the echo will be slightly better.
