I purchased a pro 78 maybe not quite a year ago and have been very happy with it. In fact I was so pleased with it that I purchased a XTR695 and just received it in the mail today. What I found, though, was that the suction cups for the XTR 695 are much smaller and what I would consider inferior to the suction cups I received with the pro-78. I'm wondering if anyone else has noticed this or has any idea for the reasoning behind this? I think the size and the strength of the cups I got with the 78 are much better than what I have gotten with the XTR, and I'd like to have the same thing for both of my RD's. Do auto part stores have suction cups that I can use to replace these smaller ones I've gotten with my XTR?
