Would HMT or Club Data be absolutely necessary?

[LEO MODE]

Each launch monitors always have ball data, but seldom has club data or both data.

I just want to know if I were to get GC2, would it be really important to get HMT, or club data.
The reason why I'm asking this is, I know club data is important. But GC2 is very well respected in the market for its accuracy that, without club data you would have realistic outcome (both in path/trajectory and ball information).

For simulation games, sure you might not need the club data since all we really care about is ball flying on the fairway.
But is it 100% accurate like Trackman? Perhaps not since it doesn't have club data or it doesn't track ball all the way.

I just want to know if I were to get a GC2, would I really need to have HMT to really have a complete experience in both practicing and simulating.
I have a Trackman 4 but I don't think I'll be able to use it for indoor because of space restriction. So I'm carefully thinking about getting GC2 as my next alternative, and HMT if necessary.

Your feedback would be greatly appreciated.

Thanks.

I know the GC2 and HMT work independently of eachother. Meaning the addition of an HMT unit will not increase the GC2 units accuracy in any way.
As for the importance of club data? To each his own.

The GC2 is very accurate for ball reading making it great in doors. If you have a TM4, you don't need a GC2 unless your space is small. You can also use the TM4 for club and GC2 for ball in doors.
