So Tosh, Is most of your round in Chepstow?
Yes, mate, Chepstow and Caldicot.
But with regards to you going WFP, on one-hand I hate saying, 'buy the Shurflo', just in case you don't get on with it.
Then on the other, I always think a backpack won't ever go to waste. Even when your van-mounted; there'd always be somewhere where it'd come in handy.
A couple of guys here with a high-quality round have said they don't use them much anymore and prefer their van-mounted systems.
But on the other hand, I know of one guy here who says he rarely uses his van-mount and prefers the backpack.
So a lot is down to individual choice, type of round and budget.
