In very few cases are the legend tees shorter than the masters, I can think of 2 off the top of my head but not any more.
In terms of the wedges. People tend to forget that they have a wedge in their iron set that you buy...........the Pitching Wedge. When players talk about four wedges we are generally talking about a bag that contains..............Driver, 3 wood, 3 - 9 iron and PW, 3 lower wedges, in my case 56 / 60 / 64 degree. The key is to keep the space between your clubs as consistent as possible.
My driver is rated at 287 and three wood at 240.
My 3 iron is 225, 4 210, 5 195, 6 180, 7 165, 8 150, 9 135, PW 120.
My Wedges are 100 80 60.
With the ability to punch you make it so those gaps are less and spin helps close them even more.
From the legend tees, you miss more greens and thus use your wedges more, often from sand and deep rough so you want wedges that work well from those areas too.
