Interesting, but I wouldn't bother with it (personally).
1. latencies matter more. PTCL generally has decent latencies to many servers around the world vs. Transworld - for e.g., Microsoft's datacenters. Increasing the speeds won't necessary change the web surfing experience. Other latencies, however, are better on Transworld - but not enough to make a measurable impact on your web browsing.
2. Some networks/routes are congested, so even if you get a 100Mbps connection, your throughput is choked by either the destination server, or some other router in between mucking things up. The only way to fix this is to use a VPN.
I remember using a 5 Mbps connection in the US (on fiber) - the web pages are much more responsive since the servers and everything are in the US. For us, we get routed to the closest data center (either somewhere in the Middle East, Europe or Singapore). Transworld generally prefer Singapore datacenters than European ones (and very, very few are linked to the Middle East). That added latency is evident.
But if you're a downloader, then by all means download away at 35Mbps!
