Long time lurker, first time poster.  I’m looking to replace my current irons (Wishon 550c’s 4-PW) and looking at the TS3s.  The Wishons have classic lofts (PW-48 deg., 9-44 deg., 8-40 deg., etc) and the TS3s have modern lofts (PW-44 deg., 9-40 deg., 8-36 deg. etc) with a GW at 48 degrees.  To match my current set, would it be recommended to go with a TS3 set of PW-4 to match clubs numbers or GW-5 to match loft?  How much would the shaft choice go into that selection? (My 550c’s have the Wishon Series 5 shafts Stiff)  I’m looking at the FST Pro115 or Pro125 shafts.  (I had the old Royal Precision Rifles 6.0 in a previous set.  I was going to go with them in the 550c’s but the Series 5 felt good.  No sense to change if it was working.)

Additional Info:Surrounding my irons are TSW wedges (52, 56), 3h and 3h (Wishon 321 Li 21 and 24 deg. respectively).  I swap between the 4h and 4i depending on conditions.
