[Rhodes22-list] traveler and tiller tamer upgrade questions

[bgreenwald at optonline.net]

I am working my way through my spring commissioning 
list and have two "upgrade" (hopefully) items I need a little 
help with.

First, my traveler was delivered with lines that were too 
short so I have decided to convert to a single line system.  
As best as I can tell, the exisitng lines are 1/4 in and, while 
the fit through the traveler bar is extremely tight, I assume 
this is what I should spec for the replacement,  I am at a 
loss as to what type of line I should use.  The catalogues 
are just a puzzlement to me - too many choices - and the 
folks at WM weren't particularly helpful. 
 I am also curious the lenght of line used by those who 
have already done this.

Second, I plan to install the Davis Tiller Tamer which calls 
for installing clam cleats on the top lip of the aft seatback. I 
have never drilled or screwed anything into the fiberglass 
and would like some advice as to how best to avoid any 
damage - cracking, etc.

Thankd much in advance for your thoughts on either 
question.
