Personally I would never carry 5 wegdes, That's a small part of why I won't go T200. Haha

I think having that many wedges would be redundant... but I use my 54° from 105yds down to 50yds.

I guess your PW would be like a 9i and such... I just feel like the AW and Gap would be redundant. Unless you really full swing everything? And is is a T100 AW or a Vokey 48, because those will go 2 different yardages...

I would not bend the T100 stronger, if anything I'd weaken the T150. But you don't really know if you need to or not without a gapping session...
If I had to... I would do 44°, 48° (1° weak), 54°, 60°.

You really just need to get a gapping fitting to see where your yardages are actually at.

THe old 4 dgree rule is just that.....old.
Focus on the yardage gaps. Different model clubs are going to give you different yardages.
For example, my T200 P is 43 and the gap is 48. I had a 52, 56, & 60 wedge at first but didn't take long to find out the 54 & 58 were a better fit for my yardage gap. Don't carry a 60 anymore. I can open up the 58 and get the same result. In the end it depends on your individual results.
