String rollers

[Farrell]

I have not used my roller on my restringing jobs because I feared that I
would be forcing the string into the forward edge of the bridge top, perhaps
enough to cause a bit of damage to the bridge (fast-track bridge-top
string-grooves). I'm really not sure how much damage that could do, because
I have not done it and then removed the brand-new strings to look (would
seem kinda criminal). Do you think such fears are unfounded? I think this
thinking is in line with Ron N.'s philosophy of not stretching strings by
pushing with a brass rod when doing pitch raises because of the same concern
(his post on this made so much sense to me that I stopped doing that). Ron?
