By all means, try one - and they are not all alike
As Holli mentioned, there are diffs. between the wedges. Most describe them as lacking feedback. I have an old sheffield smiling wedge (Eyre), and a modern wacker. The Eyre is void of feedback, but very comfortable. The wacker is quite vocal, though some would say it's more hollow than a true wedge.
As to an experienced user and a wedge - you might want to see JimmyHAD's review of the wacker 2 pc set - wedge & 1/4 hollow. I have the 1/4 hollow from the set, and it currently enjoys the status of most favored blade. Jimmy mentioned the shave of the wedge was 'better than the spanish point...' I bought the stosser wedge, and it enjoys the #2 spot on most favored blade. I've not used the old sheffield blade more than twice.
For reference, I'm not very experienced, so the heavy grind is easier for me to use. Unless you wish to keep the herd very small, I'd definitely recommend at least trying one wedge. Maybe check the area around you for other guys that might let you try theirs?
