For a x16xe. Pro's and con's for each? If you had the option which would you buy?

Few details:

Both stainless
Both average gain manifolds (nothing special)

The two in question

4-1

4-2-1

So its either a case of off-the-line speed or pulling all the way to the limiter?

Ye thats what im thinking ive got a mantzel replica so that increases top end so ideally the best thing would be to go for bottom end so its smooth all the way round.

Get 4-2-1 and get a lightened flywheel, the flywheel alone wil make an unreal differance believe me.
