Which shower cap?

[lawtoma]

For a S3 with standard (non-FIA) roll bar and mirrors on the doors?
- Standard vs long nose
- SBFS vs Thudersport (Without opening cans of worms about response times/customer service please)
Any owners' experiences welcome to help me make a decision.
Thanks!

Thanks all!
With door mirrors, am I right in thinking the standard SBFS long nose is the one I need? (rather than the upgraded version?)
