Had these with my 4/2 set up on the bus. Pulled up great and cheep cheep.
No 4/2 pot set up is going to be fade resistant at 150km+ stops, especially after a few in a row.
Adam at tuspeed is great to deal with and will have them at your door within 2 days. If you spend enough you can usually bargain with the postage...
