It may be worth noting that HiperBatch only caches the data component of a VSAM cluster indeed making it quite useless for direct/random access.
DFSMS SMB makes LSR in batch real easy to use - but it is a Local Shared Resource; in case many users need to access/update the VSAM cluster at the same time - RLS may be another option to consider.

It is a "stabilized" product no longer being actively updated. We use it for one particular file used across many applications, but that is the only file we can use it for since it is a large file (> 1.5GB). Also Hiperbatch works well for sequential access, but random access does not seem to benefit as much. Batch LSR works very well for random access (we use it quite a lot), but you may instead want to investigate the much newer System-Managed Buffering (SMB) capability, documented in the JCL reference and user guide manuals (cf. DD parameter AMP, sub-parameter ACCBIAS et. al.).

What (if any) are the recommendations, pitfalls of each or is the another option to do this? We are running z/OS V1.13.
