Rockwells?
Ironbutt we (most of us) will try issue a slower speed if you are on a downwind and it is anticipated ur heading for a 20 miler downwind, the curve ball comes in when there are more behind. then everyone slows right down (rather that than everyone head out 20 miles). As you can imagine the decsion on a speed has a snow ball effect therefore it needs to be corrrectly applied (and adhered to by you guys).
Chaps still going to Rockwells? If so what time?
