H + Sons tube bursting!

i have gone through 4 inner tubes now on my new H+sons rims and still have no tire on the bloody thing.
after the first blow out i took extra special care in making sure there was no pinches. but again, BANG. it looks like they are going on the spoke holes. so im gonna try some rim tape. how ever i never had to do this on my velocity deep Vs.

Has anyone else had these problems?

im fitting Vittoria zaffino tires and using specialized 700c 20/28 long valve inner tubes.

rim tape and then hope!

Seriously, get some tape, or at least wrap the insides of the rim a few times with the insulated tape of your choice. I also assume you're checking the inside of the tire walls for glass and thorns?
