I got myself an Acclaim sand wedge when they first came onto the market about 35 years ago. This is the most useful club ever. It will get out of steep bunkers and goes through the deep rough with regular and predictable ease. It has a rounded face with a large sole area. The head is heavy and solid which cured my habit of decelerating when playing out of sand or deep rough. Once you start the downswing it is difficult to slow it down and it cuts through sand or rough. Contrary to other posts it is easy to manipulate the face and I find it very flexible. Any lob shot, 5 yrds to 100 yrds, it is my go to club.
After 35 years I still won't trade this for any other wedge on the market irrespective of brand or price.
