I have a Trygstad 880 with race crank,Been happy with performance, I,m now building a SHR 860 to have ready to stab when this motor goes, I think all these builders are a credit to the sport,Every motor has pro,s and con,s.Will get a chance to make a real comparison, I expect they will both have simular performance advantages.Clearly both builders are extremely knowledgable,Head to Head![/QUOTE
