IsoAcoustics Gaia-Titan Theis for Magico S7s

Hi ordered a pair of Magico S7s and I am considering getting IsoAcoustics Gaia-Titan Theis for them.  I have hardwood floors and presently have Gaias for my Magico S5s.  The price of the Magico Mpods seems excessive and I can equip the S7 with the Gaias for about $1,700.00. Anybody have an opinion on getting the Gaias for the S7s. The other advice I seek is in regards to attaching felt sliders under the Gaias so the S7s can be easily slid on the hardwood floor.  I did it to the S5s and I think it works well but the S7s are about 300 pound each.  Thanks.
