Chandra and XMM are extending the minimum luminosity to which X-ray clusters can be detected and analyzed at intermediate redshifts, probing masses characteristic of poor clusters. Strong lensing systems with image separations in the range 6"-16" are starting to be detected thus opening also with this technique a new window of exploration in this crucial mass range. An unprecedented opportunity of X-ray-lensing comparison is therefore opening in an unexplored lower mass regime compared to the one of massive clusters. Therefore, we propose a snapshot survey of 5 promising strong lensing poor clusters to secure their X-ray fluxes. Deep follow-up exposures with Chandra will then be proposed for detailed analysis of the mass profile.
