I will be upgrading my scope soon and I've been looking at alternatives for guiding setups. I am currently using a piggybacked 70mm refractor for guiding with fairly successful results, however I am wondering if using an OAG would yield better results. The problems with what I believe to be differential flexure give me inconsistent results.

The results from this website seem very good comparing the two guiding techniques and without a doubt the OAG technique is much more consistent.
My plans are to upgrade to a GSO RC and I am considering using an OAG with it. Would it be recommended to use an OAG for guiding? Are there any reasons why I should not?
Thanks.
