I take it the Judo didn't work out from 6 months ago or so?
In terms of "if they mesh", you're likely to get a few different answers. One camp says they work very well together, as they are fairly different in terms of range and techniques (grappling and striking/kicking), others will point to these two arts as being cornerstones of MMA training (which isn't entirely true, but that's kinda beside the point), others still will point out the issues of cross-training, especially early in your career.
The big thing will be what you are training for. Both these systems are more sporting systems, will feature similar training methods (sparring, conditioning etc), get you fairly fit (ring fit, really), and so on. So if this is what you are after, it can be fine. If you are after "self defence" (whatever that means to you.... it really should be noted that few people who train for self defence know what it is about, and look purely to techniques and ignore what it's actually about, to be frank), pretty much any art can be fine (leaving off ones focused on such things as use of sword or traditional archery and so on, although they can still impart skills that translate quite well) provided the training is geared towards your intended uses and reasons.
So, I know you're young, and probably still a little in love with something you don't really know, but the first thing is to determine what you are wanting out of the training. From there we can start to say whether or not it's a good match for you. Make sense?
Small edit here: In a previous post (April this year) you said you were 16, and had typed incorrectly on your registration, you are now saying you're 15? You do know that this forum requires members to be at least 16, yeah? Can you clarify that for us?
Oh, and in regard to the school? Not impressed with anything I saw there, from the 5 year old kid with a "samurai sword" (taught as an "advanced" weapon.... to a 5 year old?), the pictures that don't match much of the martial arts listed, such as Krav Maga, the comments about being leaders due to their "standards", the Black Belt contracts.... it really didn't impress me at all...
