Vixen 130 sf questions - central obstruction

I am thinking of purchasing a Vixen 130sf and was wondering if anyone has had a chance to use one? It looks like a nice lightweight reflector and I have not been able to find many reviews. The one I did was positive about the scope.
The reviewer did mention that the central obstruction was 35% as it is set up for photography. I am stricly a visual observer and wondering if I should be concerned about such a large obstruction?

I was considering Starblast ota but the Vixen is an f/5 which should give better views across the eyepiece field I would think. Thanks.

I forgot to mention that I am going to mount the scope on a microstar and my tripod is not very heavy duty so I am trying to keep the ota total weight under about 8 lbs. Thanks.
