For playability and functionality...not really. The Pro are very nice looking drums but the heads and triggers on the Giga-pro are the same supposedly. One thing you can look at is getting the Studiomaster setup. I have this one and I love it. It uses the snare of the pro and the giga-pro but uses accupads for the toms. It has black cymbals instead of gold. The only big difference really is the studiomaster does not come with an stand up kick pad. It uses a kick trigger which really doesnt change much except for feel is slightly different and it looks like you dont have a bass drum. You will defintely are making a good choice by going with Hart. Good luck.

Well...first reason for me....price.
I have a GigaProTE3 with a Roland TD-8 module.
I don't really care that PROs they had the fake shells...it was a moot point...it's the sound and feel I was after. I use them in my home studio fo practicing and for recording basic arrangments before submitting them to anyone.

I do like the ECymbalII's ( the more "cymbal looking ones of that line" ) because they help me "feel" like I am playing acoustic drums...oh and i think they look cooler too.  

I have not experienced the problem jjordan speaks of, but that could probably be correted by tweaking the sensitivity a bit, although it would probably take a while to find a happy medium so you don't loose the orginal feel you had.

I mostly aggree with sjm1112...the only diffrence is aestetics. Personnaly I chose the GigaPro FOR the standup kick drum module. I wanted to emulate the acoustic feel as much as possbile and just didn't get that from kick trigger....YMMV.

Good luck with your decision, and if you choose a set that has NOT been reviewed here..please put one up...always interesting to hear a review.

I have tried the tweaking route, but without success  
And I definitely agree that the rack adds to this situation.

Those plastic shells are so sensitive.  I can tap the outside with my finger and the plastic one triggers, but the steel alloy one doesn't.  

My remedy(s) have been to trim the low frequencies back and/or to position the speaker differently.

sjm1112, are your plastic shells this sensitive?
