There is few in that category
- Epon 210KGX wedge. Had the 208KGX and loved it. Bought the 210 version thinking it would be better (newer) and hated it. Felt bulky.
- Crazy 435 black limited. Loved the looks but just did not perform for me. Feel wasn't good either.
- Jbeam ZY-7 driver. After owning and loving the ZY-11 I thought the ZY-7 would be good. Not for me. in fact, very similar IMO to the Crazy 435 black.
