OS32 is smooooooooooooth.

OS37 is not quite as smooooooooooth, but has loads of grunt.

Irvine is just 'ok'.

OS32 but an OS37 is miles better, need all the power you can get in a 30 so an OS50 Hyper is even better again

I have an OS 37 in my raptor and the question I get at the field is " Is that a 50?"

I'd go O.S if I was you seen a couple of the Irvine 36's just die....

O.S definatly smoother and a better engine overall.
