V Groove or Serpentine?

I hate March set ups. Just my opinion but I have installed more of them than most folks id bet. (March stuff is ok quality and their fit is, eh...... kinda ok (some are fu@ked and dont fit).....price wise its middle of the road. Some engines dont allow for true serpentine set ups with their system. They tend to ise belts that are a PITA to find (special order belts) ugh... ) i can probably go on but i wont.

On that note im not a fan of serpentine set ups for a few reasons.
1. Weight. Lots of extra parts required with serpentine set ups
2. Redundancy. You dont get any with a serpentine set up.
3. They dont look right on old cars.

All just my opinion but you did ask for opnions so. ..
