Which MagSafe to get for MacBook 13'' White (MacBook4,1)

I wanted to replace my fraying T-style 60W magsafe for my 13'' MacBook and I have been advised to use the 85W version to be easy on the adapter. I have also read on Apple's website that I can use a 85W magsafe instead of 60W magsafe (its original). I have also read that the charging unibody in the newest macbooks is shallower than the previous models of white/black macbooks. Does anyone know whether newest L-style 85W magsafes are compatible with early 2008MBs?

Also, should I get the T-style or L-style magsafe, I have read mixed reviews on that one as well. Some say that the new L-style is much better but some others are saying T-style may fray but at least it charges the battery. (those complaints were mainly on 60W L-style Magsafe)

Thank you in advance.

According to the details for the 85W version, it is for MBP 15" and 17". The 60W is for Macbooks and 13" MBPs.

I don't know what you mean by "T" style and "L" style.

Just get the 60W.
