If you're going HEN you're going to have to install HFW either way. Might as well just install the 4.88 HFW imo. You don't need to install the 4.88 OFW first, you can just go directly from 4.87 OFW to 4.88 HFW.
The main benefit is you can go online without spoofing if you're current and from what we currently know spoofing sounds like it's more likely to get you banned since the 4.88 update. So might as well just be current.
