As many above I've always used the standard HW as my go-to.......

I recently splashed out on an HW XL (the full size one) and did a side-by-side comparison on my FX Wildcat.

The XL was quieter...... but given the fact it's a lot fatter than the standard HW and a lot more expensive, I doubt I'd buy another without a specific reason.

I'm yet to try the XL on my FAC R10 - that will be a real test!
