Popular tips for that size bore are usually spinfit or sony hybrids, if you don't get a good fit or enough isolation you should look in the direction of foam or triple flange tips. 

Yeah I ordered the Sony. They will be here next month
 
I did buy the westone's anyway because I missread what fnkcow wrote. I thought he wrote the "foams" where made for 5mm driver and the "silicone" were for the smaller drivers. While the silicone tips are smaller the foam tips don't even come close to fitting a 5mm driver.
 
All was not lost though because I ripped out the foam core and put in a core from another set of tips and the results are amazing
