exact irons i've played for years before dipping into the Maltby waters. the spec sheet doesn't list offset, but i'd say its pretty generous just looking at them. KE4 Max looks like a very similar spec...
i'd go with the set gap wedge if you use it as a full swing club. the set GW in the TS1-IM is a cheat code for me, both full swing and chipping around the green. i can't imagine the TS3 performs any different.
