Thanks for the advice guys. I've signed up on Vandem's mailing list, just waiting for my 50% off everything I want to buy offer
Looks like I should forget the Randals and go for the Sabres which I'm more than happy to do after reading your collective experiences. I like the idea of switching base plates, if for no other reason than giving it a try. Except 38 degree base plates are the forged expensive type 28 quid or 65 for the super spendy awesome forged 38 complete truck... Ouch, the whole lot's adding up to "how am I gonna hide this lot from the wife!"
The Hollowlite 180's seem a bit more wallet friendly but only at 48 degrees are not really what you guys are recommending, likewise the bears are 52 degrees but do look good.
Hmm plenty for me to think about, any more advice is welcome.
Edit: I've found some Bear grizzly 840's for reasonable money, ideally I'd like to try different angle's but am struggling to find trucks and compatible base plates in the cheaper trucks.
