Klipsch FII's with mods vs. FIII's


I am not sure if I should buy a pair of Klipsch Forte II's and do a Crites crossover and Ti  tweeter upgrade, or get a used pair of Forte III's. I read that the III's have an upgraded mid horn, has a better crossover and titanium tweeters. It would run about $1600 more for the III's after the FII upgrades. Question is, do I approach the sonic quality of the III's for less money upgrading the II's?  Is it close enough to save the bucks and use elsewhere? I'll be powering them with an integrated Mac 6200 putting out 75w/8 ohms. 
Thanks

@ozzy62, did you build out your GR Research Super V’s yourself (with one of the H-frame flat packs that were available), or buy them from someone else who had done it? I didn’t go for the Super V (I’m a diehard planar man), but did for the OB/Dipole Sub that is included in the SV. Fantastic bass, which few have had the pleasure of hearing. Audiogon member kennythekey emailed me after I had described and recommended the OB/Dipole in a sub thread, and ended up contacting Danny Richie to get himself a pair, and loves them. Readers, to see them for yourself look up "Kenny’s System" in Virtual Systems. The only OB/Dipole Servo-Feedback sub on the market!
I bought them used. You are right, there is nothing better than servo controlled OB bass.

So I went and auditioned the 1991 Forte II's today with no mods.  I had not listened to Klipsch speakers, La Scallas & Kornerhorns, in 30 years. I wanted to like them but.....I found the highs too bright for my liking, just like 30 years ago. I listened for a long time and they tired me and I wanted quiet !!  I believe I'm not a tweeter and/or mid horn guy. It's been almost 20 years since the now resurrected Forte III's. Can I, should I expect anything different? Or is a horn is a horn is a horn? Don't know if I can even find an audition for them. 

Depends on what was in front of the speakers. They need good quality amplification (think tubes) and a good source. Describe what the ancillaries were.
